Numerical Simulation of Effect of Some Technical Factors on Melting Process of Ferrosilicon in Liquid Iron

The effects of technical factors on melting process of ferrosilicon in liquid iron are studied by using numerical simulation.Two separate periods are identified:the iron shell period and melting period,after immersion of ferrosilicon into liquid iron.Also,it is shown that the rise of initial temperature of liquid iron,decrease of ferrosilicon size and increase of silicon content in ferrosilicon are to shorten time from initial immersion of ferrosilicon into liquid iron to its complete melting.If two separate periods are considered respectively,the effect of initial temperature of liquid iron and ferrosilcon size on the iron shell period is great,but on melting period small.
